If your current RV air conditioning unit struggles to cool in high heat, draws too much power, or leaves you frustrated every time summer rolls around, it’s time to compare upgrade options that actually deliver comfort and efficiency.
In this guide, we’ll break down Furrion Chill® Cube, Chill HE, and Chill HE low-profile RV air conditioners in real terms — purpose, performance, size, efficiency, and which RV types they work best in — so you can confidently choose the right solution. With clear differences and direct answers, this comparison helps you move past underperforming ACs and into smart, lasting climate control.
Meet the Furrion Chill RV Air Conditioner Lineup
Furrion’s RV air conditioner family gives you options for different climates, RV sizes, and clearance needs:
- Chill Cube: Premium performance in very hot weather, optimized for efficiency and quiet operation using variable-speed compressor technology.
- Chill HE: A high-efficiency, dual-fan system that balances performance, cost, and everyday comfort with broad compatibility.
- Chill HE Low-Profile: A clearance-friendly design for smaller rigs, providing efficient cooling and adaptable climate control with reduced roof height.
All three fit standard 14" × 14″ rooftop cutouts, making them compatible with thousands of trailers, 5th wheels, and motorhomes.
Chill Cube vs. Chill HE: What’s the Difference?
The main difference between Chill Cube and Chill HE is cooling performance and power efficiency. Chill Cube is a premium, variable-speed system built to deliver consistent, powerful cooling, even in extreme heat, while using up to 40-50% less power than traditional rooftop units. Chill HE, by contrast, is a high-efficiency dual-fan design that replaces and upgrades factory air conditioners for everyday RV use.
Chill Cube: Power Where It Matters Most
Chill Cube is engineered for RVers who refuse to compromise on cooling performance, even in extreme heat. When outside temperatures climb past what traditional rooftop air conditioners can handle, Chill Cube’s variable-speed compressor technology steps in to deliver consistent comfort with significantly less power demand.
Unlike fixed-speed RV air conditioners that cycle on and off at full blast, Chill Cube continuously adjusts compressor speed based on real-time cooling needs. This allows the system to deliver over one ton of cooling capacity at temperatures above 105°F while using up to 40-50% less power than conventional rooftop units. The result is faster pull-down, steadier interior temperatures, nearly noiseless operation, and improved humidity control without the disruptive starts and stops that frustrate many RV owners.
That variable-speed operation also translates directly to power flexibility. Chill Cube softly ramps up amperage instead of spiking it, which reduces the risk of tripping breakers and eliminates the need for aftermarket soft-start devices. This makes it a strong choice for RVers who rely on generators, inverters, or limited shore power, especially during off-grid travel.
From a design standpoint, Chill Cube balances performance with practicality. Its aerodynamic rooftop profile reduces wind resistance, supports better fuel efficiency, and leaves room for solar panels or pop tops. Inside the RV, continuous low-speed operation improves dehumidification, helping eliminate the clammy feeling that often lingers when standard ACs short-cycle in hot, humid conditions.
Best suited for:
Large RVs, motorhomes, and campervans operating in hot climates or demanding conditions where cooling reliability and power efficiency are critical.
Important consideration:
Because of its high capacity, Chill Cube is positioned as a premium AC and is not recommended for very small rigs where cooling needs are modest.
Chill HE: Balanced Cooling for Everyday Adventures
Chill HE is designed for RVers who want dependable cooling performance without stepping into a premium, variable-speed system. It strikes a balance between efficiency, airflow, and ease of replacement, making it a popular upgrade from factory-installed or aging rooftop air conditioners.
At the core of Chill HE’s performance is its dual-fan design, which improves airflow and cooling efficiency while reducing operational noise. One fan drives cold air into the living space while the other circulates air around the primary system components. This helps dissipate heat more effectively, reduces strain on the compressor, and results in smoother, quieter operation compared to single-fan units.
Available in 13.5K and 15K BTU configurations, Chill HE fits a wide range of RV sizes and layouts. It supports both single-zone and multi-zone setups, giving owners flexibility to match the system to their interior layout and comfort expectations. Its mid-profile, aerodynamic housing helps limit wind drag, contributing to better fuel efficiency during travel.
Best suited for:
Travel trailers, 5th wheels, and motorhomes where owners want a noticeable upgrade in efficiency, noise reduction, and cooling reliability over standard OEM air conditioners.
Important consideration:
While more efficient and quieter than many factory units, Chill HE uses a fixed-speed compressor and is not intended to replace Chill Cube’s extreme-heat, low-amperage performance.
Chill HE Low-Profile: Efficiency With Roof Clearance in Mind
The Chill HE low-profile AC is purpose-built for RVs where rooftop height and aerodynamics are as important as cooling efficiency. By lowering the overall profile of the air conditioner, this system reduces wind resistance, improves clearance, and supports energy-conscious travel without sacrificing comfort.
Designed for small to medium RVs, the low-profile unit is available in 13.5K and 15K BTU options and uses a dual-motor system to deliver efficient airflow with quieter operation. Its adaptive control capabilities allow the system to automatically switch between cooling, fan, and dehumidification modes based on interior conditions, helping maintain consistent comfort with minimal manual adjustment.
The reduced housing height doesn’t just improve clearance, but it also helps minimize drag while driving, which can contribute to better fuel efficiency over long distances. Inside the RV, the system supports ducted and ductless configurations, making it adaptable to a wide range of layouts while fitting standard 14" × 14″ roof cutouts.
Best suited for:
Smaller travel trailers, campers, and RVs with height restrictions, storage constraints, or a strong focus on efficiency and quiet performance.
Important consideration:
Low-profile systems are not recommended for large 5th wheels or RVs with high cooling demands, where a standard Chill HE or Chill Cube system is better equipped to handle the load.
